u
Select [diS] and set the update rate and orientation of the display:
• [d1]: update of the measured values every 50 ms.
• [d2]: update of the measured values every 200 ms.
• [d3]: update of the measured values every 600 ms.
• [rd1], [rd2], [rd3]: display as with d1, d2, d3; rotated by 180°.
• [OFF] = The measured value display is deactivated in the Run mode.
When one of the buttons is pressed, the current measured value is displayed for 30 s. Pressing the
[Enter] button again activates the display mode. The LEDs remain active even if the display is deacti-
vated. Error messages are displayed even if the display is deactivated.

10.3 Set output signals
10.3.1 Setting of the output function
u
Select [OU1] and set the switching function:
• [Hno] = hysteresis function/normally open.
• [Hnc] = hysteresis function/normally closed.
• [Fno] = window function/normally open.
• [Fnc] = window function/normally closed
• [Off] = output off.
[OU1]
u
Select [OU2] and set the function:
• [Hno] = hysteresis function/normally open.
• [Hnc] = hysteresis function/normally closed.
• [Fno] = window function/normally open.
• [Fnc] = window function/normally closed
• [I] = current signal proportional to pressure 4…20 mA.
• [InEG] = current signal proportional to pressure 20…4 mA.
• [Off] = output off.
[OU2]
10.3.2 Set switching limits
u
Select [SP1] / [SP2] and set the value at which the output switches.
[SP1]
[SP2]
u
Select [rP1] / [rP2] and set the value at which the output switches.
rPx is always smaller than SPx. The unit only accepts values which are lower than the value for SPx.
[rP1]
[rP2]
10.3.3 Define switching limits for the window function
u
[ou1] /[ou2] must be set as [Fno] or [Fnc].
u
Select [FHx] and set the upper limit.
[FH1]
[FH2]
u
Select [FLx] and set the lower limit.
FLx is always lower than FHx. The unit only accepts values which are lower than the value for FHx.
[FL1]
[FL2]
10.3.4 Scale analogue value for OUT2
u
Approach the desired minimum system pressure in the installation and keep it constant.
u
Select [tASP] with [Enter].
u
Press [▲] or [▼] until [----] is displayed.
u
Confirm [----] with [Enter].
w
The current pressure is defined as start value for the analogue signal.
